Phasors

The phasors represent voltages and currents as complex values with magnitude and phase angle. Amplitude and phase are determined from the filtered fundamental oscillation signals. The phases are determined in comparison to a synchronous, time-synchronized reference and displayed as complex pointer variables. The phasors are updated at a defined rate, which is defined via the parameter PhasorReportingRate.

The phasors enable a compact description of multi-phase systems and form the basis for power flow analyses, grid protection and synchronization tasks.

The measured values are provided via the STcPowerMeasurePhasor structure.
